Patent Claims
7 claims

Legal claims defining the scope of protection, as filed with the USPTO.

2

2. The display device of claim 1, wherein a pixels per inch (PPI) of the second pixel area is less than a PPI of the first pixel area.

3

3. The display device of claim 2, wherein the touch sensor driver is configured to transmit luminance control data for controlling the luminance of the second pixel region to the luminance control device.

4

4. The display device of claim 3, wherein the luminance control data includes frequency data indicating a number of touch inputs generated on the second pixel region, and touch coordinate data for touch inputs in the second pixel region.

5

5. The display device of claim 1, wherein the luminance control device is configured to control the luminance of the second pixel region to be less than a luminance of the first pixel region when a number of the touch inputs on the second pixel region is greater than or equal to a preset threshold within a predetermined reference time.

7

7. The mobile terminal of claim 6, wherein a pixels per inch (PPI) of the second pixel area is less than a PPI of the first pixel area.

8

8. The mobile terminal of claim 6, wherein the luminance control device is configured to lower the luminance of one of the first pixel region or the second pixel region having a lower pixels per inch (PPI) when a number of the touch input is greater than or equal to a preset threshold within a predetermined time.

9

9. The mobile terminal of claim 6, wherein the luminance control device is configured to lower one of the first pixel region or the second pixel region having a lower pixels per inch (PPI) in a gray scale equal to or greater than a specific gray scale of a maximum frequency among gray scale values of pixel data to be written to pixels of the pixel region having the lower PPI.
